Subject: [PATCH 04/15] efi: types: document efi_physical_addr_t being always 64-bit
Date: Tue, 27 May 2025 23:22:49 +0200 [thread overview]
Message-ID: <20250527212300.575031-5-a.fatoum@barebox.org> (raw)
In-Reply-To: <20250527212300.575031-1-a.fatoum@barebox.org>
From: Ahmad Fatoum <a.fatoum@pengutronix.de>
Unlike UINTN (size_t), efi_physical_addr_t doesn't change size
depending on whether the system is 32- or 64-bit.
Add a comment to clarify this.
